TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 349,621, dated September 21, 1886.

Application filed December 8, 1885. Serial No. 185,039. (No model.) 7

To all whom it may concern.-

Be it known that I, JOHN F. WoLLENsAK, a citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Transom-Lifters, of which the following is a specification.

The object of my invention is to make a transom-lifter which will permit the transom to be opened and fastened at any desired de gree of openness; and my invention consists in the features and details of construction hereinafter described and claimed.

In the drawings, Figure 1 represents a side elevation of my transom-lifter attached to a transom and in place, and Fig. 2 represents a perspective and enlarged view of the lifting.

rod and the fastening or locking bracket or holder.

A represents the transom-lifting rod; 13, the fastening-bracket; 0, holes in the lifting-rod, and D a tongue or projection on the lockingbracket, adapted to engage with the holes in the liftingrod.

In making my improved transom-lifter I make a lifting-rod, preferably rectangular in form, and provided with a hole or a series of holes at proper intervals apart. I make a guide, bracket, or locking-piecc with a hole in it, through which the lifting-bar may move up and down as the transom is opened or At one side of the hole in this locking-bracket I provide a tongue or extension of the right size and shape to fit into the hole or holes in the 1iltingbar. Instead of holes, notches may be made, in which case the tongue orprojection on the locking-piece will be adapted to engage therewith. It will be ob served that the liftingbar is of greater diame- This enables me to make the necessary holes or notches in the lifting-bar without rendering it The locking-bracket is made of two main pieces at substantially right angles to each other. The vertical portion of this bracket is made to permit of its attachment to the casing of the door or other article in connection with which it is to be used, and the horizontal portion is provided with a hole or opening in which the liftingbar is placed, and in which it slides 11p and down as the transom is opened or closed. EX- tending from one sideof this hole or opening is a tongue or projection adapted to engage with the holes or notches 011 the lifting-bar and hold itin any desired position. These features of the lifting-bar and the locking-bracket will be clearly understood by reference to' Fig. 2 ofthe drawings.

In operation the transom is opened or closed by moving the lifting-bar up or down until one of the holes becomes coincident in position with the tongue or projection on the locking-bracket, when it is moved toward it until it engages therewith. Thistongue or projection prevents the transom,from being either raised or lowered until the lifting-bar has been moved back and off from the same, when it can be again moved up and down. In this way the transom may be opened, closed, adjusted, and locked at any desired degree of openness.

WVhat I claim is In a transom-lifter, a non-revoluble liftingbar of greater diameter in one direction than in the other, having one or more notches or holes in the direction of its least diameter, in combination with a locking-bracket having a hole or opening through which the lifting-rod slides up and down, and a tongue or projection extending from the side of such opening, to engage with the holeor holes in the liftingbar, whereby the transom may be held or locked at any desired degree of openness, substantially as described.
